i 0 allwhomit may concern:

Be it kn wn that 1, WILLIAM Dams, a citizen or the United tates, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Repeating Drip-Pan Alarms; and I. do declare the fol lowing to be a full, clear, andiexact description of the invention, such as will enable others skilled in the to which" it appertains to malre and use the same.

My invention relates to improvements in alarms or annunciators for use to give a signal of some sort when a liquid level rises beyond a predetermined extent, the present embodiment of the invention being devoted more particularly to device intended primarily for use in connection with the drip pans oi refrigerators.

One object of the invention is to provide a device of the character set forth which will repeatedly sound an audible alarm when the drip pan should be emptied.

A further object is to provide an extremely simple and inexpensive, yet a highly ellicient and reliable construction which may readily be set within an ordinary drip pan, the device being preferably weighted so that it will remain in positionwithin the pan, without the necessity of attaching it thereto, although in some instances attachment may i 01-: ctiLu be cliccted if desired.

"With the foregoing. in view, the invent-ion resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawings.

Figure l is a side elevation partly in section showing the alarm set for operation.

Figure 2 is a duplicate of a portion oi Fig. 1, illustrating the manner of setting the alarm.

Figure 3 is a horizontal section on line s s- Or Fig. 2.

In the drawings above briefly descri ed, the numeral 1 designates a standard whose lower end is here shown as provided with a weighted base 2 adapted to rest upon the bottom of a drip pan. It will be understood however that in some instances the standard might well be secured to the bottom of the pan, but it is preferable, in order that an the device, whether formed of wood or on metal, or froina combination of the two, shall be suilicicntly heavy to re; 'iin in place upon the pan bottom.

In the present SllO'filllQj the star a provided with a pair of opposed lo ar- 3 and with a pair oi opposed upper arms l, the two i 3 bein in ment with each other while h laterally offset from each other to clear a pair oi. spring arms rise from thearms The en .1 the arms 5 are provided. with clapp adapted to successively strike a gong w i is mounted on the upper end of the sta ard l. 70

For tensioning the arms 5 d successively releasing said arms, l have provided a of vertically swinging arms 8 which. a crumed to the arms d as indicated 9. lower ends of the arms 8 provided v' floats 10 while the upper ends of said a which extend above the t crums 9', force inwardly upon pins 11 carr. e by the cl appe 1 6, vhen the arms 8 rise under the i :tlu'encc or" the floats 10. Any suitable provision made whereby the arms 8, after tension the springs 5, will successively release tli so as to give two alarm signals when n 2 drip pan should be emptied. In the ent showing, one of the arms 8 is longer thu the other and this is preteraliile, but it v v be understood that the c; d could be obtained in other ways.

After the device has operated and th drin pan has been emptied, in. order to 1 .1 device, it is simply necessary to push simu taneously inward upon the two spring a 5, as indicated in Fig. 2. Thus, the pins 11 swing the arms 8 inwardly until said pins can pass over the upper extremities oi. said or) arms in condition to eng: go the inner sides thereof. The spring arms 5 are then; released and assume a substan ally vcrticu position but as the water level said arms swing upwardly indicated in Fig. 1, to place the arn s 5 under tension and to release them successively when the water level has reached the point at which the pan should be emptied.

Since excellent results have been obtainco by the details disclosed, they are preferab followed, but within the scope of the in vcntion as claimed numerous minor changes may of course be made and it will be understood that any desired materials may be used in manufacture of the device I claim:

1. An alarm 01' the class described 801T}: prising a base, an integral standard rising therefrom, a signal secured to the upper end or the standard a spring arm secured at its lower end to the standard, said arm extending in vertical spaced parallelism with respect to the standard and having its upper end terminating adjacent the signal an im- 132015'6161116I1i1 secured to said upper end to strike it, and a float carrying arm pivotally connec'ed to the standard and having its upper end engaged with the impact element to place said spring dlll'lllllClGl tension as the liquid level rises.

ii liquid level annunciator comprising a standard having opposed upper arms, opposed lower arms, a gong mounted on the upper end of said stanrrard, a pair oi spring arins rising from said lower arms and haviug gong operating clappers and a pair oi float operated arnis pivoted to said upper arms for tensioning said spring arms, provision being made for successively releasing said spring arms.

3. A liquid level annunciator comprising a base, a standard rising therefrom, a'pair o extensions projecting at right angles from the standard, a bell secured to the upper end of the standard, a pair of spr g l cured at their lower ends to the latter tne upper ends of said arms being arringce neath the bell, hainnirs secured to the named ends of the arms for striking the stop pins projecting from the hammers, a pair or float-actuated 'ar "pivoted i tween their ends on the aforesaid extensions, the upper free ends oft-he last named arms being releasably engaged with said pins. 7 V I r in testimony whereof i have hereunt aiiixed my signatur i V 7 WILLIAM E.
